By integrating the methodology of travel cost method together with activity concerned for
estimate non market benefit for outdoor recreation site a case study of park, several useful
applications can be obtained. Since the conventional travel cost method is applied to this
study has merits on the simplification of derivation, it provides results that are easy to
interpret. The actual behavior of park visitors also includes the activity on site. The
purchasing goods and service for making trips to parks are considered as one innovative
approach to estimate this benefit. The total spending model can be used to estimate the non
market benefits of park, and it also provides the useful idea on the travel and activity concerns.
The users who travel longer to park would have tendency to stay longer as well. By using this
rational result, this study also calibrated the model to determine the travel and activity factor
for different case analysis.
Based on the results of analysis, the interpretation can be discussed into two main different
categories that are users’ pattern activity at park and transportation modes to park. The
different value on different kind of activity resulted to application that policy maker or park
planners should consider providing suitable facility of different type of users’ activities. It can
be noticed that different type and multiplication of activities result to different value of
activity and distance factors. Actually this factor was obtained from the total spending on
travel and activity on site. Therefore, the value of factor can be used to reflect the benefit of
travel and activity to different users.
When this factor was applied to determine the relationship on modal usages, the number of
valuable results can be examined. Identification on value of factor in each mode is the
representative of the relationship between travel and activity on transportation means to park.
The results indicate that the different modes provide different value of factors that concern
with the accessibility to park. Indifferent benefit was employed to identify the distances that
maximize benefit to users on travel to parks by different means. For shorter distance, walking
mode is better than walking and car. However, if the distance to park is very long, users
would be willing to drive car to park instead of cycling and walking. It can be seen that the
diversity of users, pattern of activity and different modes to park result to different benefit on
park visit.
